To all whom t may concern.; l

Be it known that Fnnnnmen Birnen- MAN, residing at Portland, in the countyof Multnomah and State of Oregon,have in vented certain'new and. useful llmprove-y ments in Pastrydtdaking Machines, of' which I the following is a specification.

My invention embodies certainl nevi7 and useful Yimprovements in the machine dis?. closed in my Pate ntx:f.;':1,071,027, issued iu-r gust 26,1913 and my 'Patent :,tl'l,075,625, issued October 14, 1913, and the present invention has for the particular object to provide means for holding the batter tank from' dough can be introduced into' the tank fromv lowering until the cores have been removed therefrom and the additional. supply' of the reservoir. v

l have found, in practice, that the added weight due to the displacement ofthe cores while dipping, will `cause a. .more or less partial lowering of the tank after the" tank 'l raisingc'aln, (see Patent #1,075,625) has disengaged the rod or bar 229. rlhis Vlowering of the tank. before the coresare removed from the batter frequently results in the application of an inadequate supply of batter'to the cores and when the machine is running rapidly, the supply of Vbatter to the cores is not always vuniformly applied. lin order therefore -to overcome these obj ections, I have provided the mechanism which constitutes' .the present invention, for the purpose of holding up the batter tank for, a short interval of time after the tank raising cam has disengaged the tank arm, and until the cores have been adequately sup# plied with batter and sufficient batter has been allowed to iow into the tank from. the reservoir valve to approximate the normal amount.

lin its more detail nature,- the invention includes those novel details of construction,`

combination and arrangement of-parts, all of which will kbe first fully described, then be specifically pointed out in the appended claims, and illustrated in the accompanying drawings, in which Figure I1 isa vertical section and part elevation 'of a set of'molding devices at the loading or dipping position, the parts being inthe positioni they assume just `prior to the dipping operation.`

Fig. 2 is `a detail elevation showing the position of the dipping arm at the time the cores are to be dipped (the cores being i omitted) lshowing the I fpeciiication csf- Letters Patent. l v :ldfttlltllljtidl lbwiellagillt, ltwli'ii 'appnanbn eiekiriiireaieie. semaine. mareo. I

parts shown in the present drawing and numbered below -300maybe. of the same.

general construction, as the correspondingl numbered' parts in my Patent '#1,075,625,

save that thearm 229 is extended upwardly in such way that it can be grasped by the4 ngers 30d on the-rockingarm 303 that is journaled at 301 on a stud secured'tothev frame 23. rI he arm 303 has an extension .,302 that coperates With a second cam 300 onthe shaft 2O and is held in engagement -With such cam by a retraction spring 305.

The .operation of the parts mentioned is the same asthe correspond-ing parts 'shown in i my Patent #1,075,625, except that When the parts are positioned as shown in Fig. 2`of th'epresent drawing, the cam 300, will rock 10 the end'of the rod 229 and hold such rod the arm 303 to cause the fingers 304 to grip yafter the cam 2 30 has disengaged the arm 229 on the' return oscillation'of the varm 92.

The lingers 304 grip the arm 229 until the 15 229 and the tank 25 Will drop, subject to the counterbalancing Weight 103.

yIn this way, a more even application of the batter tothe cores is obtained, and a .more uniform product of the machine' is provFrom the foregoing description,..taken in connection with the accompanying draw.- .30
